25cc HCCI engine fueled with Diethyl Ether

Author: Lemberger, Ian Date: 2009 This research forms part of an ongoing HCCI study at the SASOL Advanced Fuels Laboratory to investigate and understand engine configuration and fuel chemistry effects on combustion in HCCI engines. This project continues from a previous project ... Read more
3-Phase gate-turn off thyristor inverter

Author: Kleyn, D A Date: 1986 The requirements of a standard 3-phase Induction Motor driven by a Voltage Source Inverter (VSI) are studied. A full 3-phase Variable Speed Drive (VSD) and its controller have been designed, constructed and tested. Gate Turn-Off Thyristors ... Read more
A 3-phase Z-source inverter driven by a novel hybrid switching algorithm

Author: Malengret, Jean-Claude Date: 2007 A 3-phase Z-source inverter has been researched, designed, simulated, builtand tested. The purpose of the inverter is to deliver 3-phase 400 VAC from aDC supply that can vary over a range of 20 to 70 Vdc. This is done with a Zsourceinverter ... Read more
3D model reconstruction using photoconsistency

Author: Joubert, Kirk Michael Date: 2007 Model reconstruction using photoconsistency refers to a method that creates a photohull, an approximate computer model, using multiple calibrated camera views of an object. The term photoconsistency refers to the concept that is used to ... Read more
3D property objects in South African local government: the necessity of representing and managing the third dimension in the City of Cape Town property management system

Author: Humby, Lara Date: 2021 The objective of this research was to analyse whether there is a need for a form of 3D Land Administration System (LAS)in South Africa (SA) based on the land administration functions of land tenure, land use, land development and land value. ... Read more
3D reconstruction and camera calibration from 2D images

Author: Henrichsen, Arne Date: 2000 A 3D reconstruction technique from stereo images is presented that needs minimal intervention from the user. The reconstruction problem consists of three steps, each of which is equivalent to the estimation of a specific geometry group. The ... Read more
3D visualisation of the laetoli footprints on the internet

Author: Taylor, Simon Date: 2000 Bibliography: p. 84-86. Read more
A 500kHz-5MHz CW stepped frequency borehole tomographic imaging system

Author: Isaacson, Adam Rhett Date: 2001 This dissertation involves a study of Cross-Borehole Tomography. The mathematical physical models of the Radon Transform are reviewed. The entire Cross-Borehole Tomographic process is simulated, based on these physical models of the Radon ... Read more
9-Phase inverter driven motor

Author: Hoffman, Keith Paul Date: 1983 The behaviour of a 9-phase squirrel cage induction motor is studied when it is excited with unmodulated and chopper modulated quasi-square phase voltages. A 9-phase bridge inverter, which produces the quasi-square waveforms, and its digital ... Read more
A Case Study on the Viability of Electricity Generated from a Solar PV Installation as an Alternative or Supplement to Traditional Electricity Supply in Existing Buildings

Author: Jooste, Van Wyk Date: 2020 This research study emphasizes the global responsibility and the importance of employing alternative sources of energy that are climate-friendly. It argues against coal-based energy creation and explains why it is not a long-term sustainable ... Read more
A Case Study to Determine if Micro-Unit Developments Create Another Step Along the Housing Ladder for Low-Income Homeowners in Soweto

Author: van Eeden, Marile Date: 2022 The South African government has been providing subsidised housing for decades, yet a large portion of the population live in inadequate housing. More recently, it has been found that many residents earn more than what is allowed to qualify ... Read more
A CFD framework for aeroelastic gust load calculations

Author: Man, William Liw Tat Date: 2018 A Computational Fluid Dynamics (CFD) framework for the simulation of the aeroelastic response of aircraft flying under gust loading was developed. The multiphysics, Finite Volume, VertexCentered code Elementaltextsuperscript{textregistered} ... Read more
A Comparative Study on Shear Strength Testing of Single and Multi-layer Interfaces using Large Direct Shear Apparatus

Author: Muluti, Shade Date: 2021 Geotechnical structures such as composite liner systems in landfills consist of multiple interfaces, which include a broad range of geosynthetics in conjunction with soil, rocks and any other related materials. This results in the introduction ... Read more
A comparative study on the structural behavior of concrete arch dams subjected to swelling due to aggregate sllica reactions

Author: Stehle, Hermann Theodor Date: 2018 South Africa is considered a water-scarce country and this fact alone stresses the absolute need to preserve its water resources. As time goes by, the ageing of dams in South Africa is becoming an increasingly important factor to consider ... Read more
A comparison between conventional brick and timber-frame brick veneer housing

Author: Mostert, J J J Date: 1978 Timber-frame brick veneer construction originated in countries in which houses were traditionally constructed with loadbearing timber frames which were clad with non-loadbearing weather boarding or similar light-weight materials. Timber-frame ... Read more
A Comparison of Wastewater Process Modelling Tools: Case Study of Potsdam WWTW

Author: Govender, Neeren Date: 2022 A wastewater process model can either be based on a steady-state or dynamic mathematical modelling approach. The characterisation of the influent wastewater and specific wastewater parameters are critical input parameters to the mathematical ... Read more
A critical review of the housing policy and the State's intervention in mining towns in South Africa

Author: Manenzhe, Thiathu Darriyl Date: 2018 Since 2012, there has been increasing government interest in mining towns. This interest was occasioned by the Marikana shooting. This interest, led by the presidency through Inter-ministerial Committee on the Revitalisation of Distressed ... Read more
A deep learning-based approach towards automating visual reinforced concrete bridge inspections

Author: Dube, Bright N Date: 2021 Visual inspections are fundamental to the maintenance of RC bridge infrastructure. However, their highly subjective nature often compromises the accuracy of inspection results and ultimately leads to inaccurate prioritisation of repair and ... Read more
A fluid loop actuator for active spacecraft attitude control - A Parametric Sizing Model and the Design, Verification, Validation and Test with a Prototype on an Air Bearing

Author: Martens, Bas Date: 2019 Active spacecraft attitude control by using a pumped fluid as the inertial mass has potential advantages over reaction wheels, including high torque, lower power consumption, reduced jitter and prolonged lifetime. Previous work addressed ... Read more
A framework for the evaluation of the structural safety of existing concrete gravity dams

Author: Dankers, Clyde Lleland Date: 2019 Addressing the aging and deterioration of dams is a relatively new challenge in the dam engineering field in South Africa. The average life expectancy of a dam is approximately 50 years, but they can normally be used for much longer periods ... Read more
